BEIJING, November 8. /TASS/. The agreement on organisation of a constitution reform in Ukraine is becoming more important now, than it was back in April, where the agreement was reached, Russia’s Foreign Minister Sergei Lavrov told reporters after his meeting with the U.S. Secretary of State John Kerry on Saturday.

The Russian foreign minister said during the talks with the counterpart they “referred to the Geneva format,” where in April in Geneva met foreign ministers of Russia, the U.S., Ukraine and the EU high commissioner.

He also said in the Geneva statement of April 17, Ukraine’s authorities undertook the obligation to begin immediately a political process, constitution reform with involvement of all regions and political forces.

“Today, John Kerry and I agreed this task is still, or even more important than it was in April, where the parties agreed on beginning of the process. We shall try to persuade the Ukrainian authorities the obligation should be observed,” the Russian foreign minister said.

The Russian and American sides discussed also necessary following of the Minsk agreements between Ukraine and the Donetsk and Luhansk People’s Republics.

“Those agreements were signed, the parties discussed measures and time frames of every agreement,” Lavrov said.

At the same time, he said, “the ceasefire, unfortunately, is not observed fully, exchange of fire continues.” He spoke about a tragedy in the school yard near the airport in Donetsk (where shelling claimed lives of school children).

“Many other incidents are happening. We believe, it is necessary to finalise as soon as possible the separation line in order to control clearly observing of the ceasefire and the truce conditions,” Lavrov said.
